For any mountain pursuit, Regulator'\\" Stretch provides clean, composed flexibility and doesn't bind up or fight against your moves. Worn as an outer layer, it can make just about any dirtbag look suave. The men's top has a durable, stretch-woven patch pocket and a front zip that's offset at the neck. The women's has a contoured fit and a deep front zip for ventila tion. Both have smooth, relaxed hems for layering or comfort under a harness.
